Well, I think me and you have had this conversation over the phone, or at least something similar to it.
It's one of those things you really have no control over. Unfortunately, if you have any type of higher standards at all related to the work you put out...being a detailer, basically leaves you screwed till you find someone that fits.
I've tried to do interviews, I've had guys come in and work for a day, I've tried craigslist ads...none of it matters. None of it brought me a guy I could trust, was reliable, or even really wanted to work for that matter.
I feel you strongly, cause I'm in the same position. I desperately need a third man...but have had no luck. So me and my regular guy have been working 70+ hour weeks trying to get it all done. I have one other guy, but he only works saturdays. It's exhausting...but customers are happy, and feedback has never been so good.
My advice, is to keep your quality intact with you and Tyson. Just work hard, schedule the work out as best you can, and hope someone comes along who is the right fit. It's like most things...if you look for it, you won't find it. Stop looking, and it will happen.
IF you do try people out...be extremely stern and express what it takes to work for you. Let them know, one slip up...and you're gone. It's not a job where you can call out, or have sick days. Obviously legitimate sick days are different...but they should be there for you damn near 100% of the time.
Be thankful you have that one guy...cause in all reality it could be worse.
